Here are some possible misunderstandings:
* Golden Apples: Perhaps you're thinking of Golden Apples. These are very rare items found in Pokémon Mystery Dungeon games and can be given to your Pokémon to boost their stats. They're definitely not as common as Ribbons, but they do exist in the Mystery Dungeon universe.
* Shiny Pokémon: Maybe you're wanting to find a Shiny Pokémon, which are very rare versions of normal Pokémon with a slightly different color scheme. These are possible to find in Pokémon Mystery Dungeon games, but not guaranteed. You can increase your chances of finding them by using a Shiny Charm item, which you can obtain from the post-game in some games.
If you're looking for a specific item or a specific Pokémon in Pokémon Mystery Dungeon, you can try searching online for specific guides or FAQs for that particular game.
